Abstract
A widely tuneable electroabsorption-modulated sampled-grating distributed Bragg reflector laser, integrated with a semiconductor optical amplifier is characterized for analog applications. The wavelength can be tuned anywhere from 1522 to 1573 nm. The suboctave spurious-free dynamic range (SFDR) is between 125-127 dBHz/sup 4/5/ measured at eight sampled wavelengths over the tuning range. The broad-band SFDR is in the range of 103-107 dBHz/sup 2/3/ limited by third-order intermodulation products or 95-98 dBHz/sup 1/2/, limited by second-order intermodulation products.
